English: With a length of 7.62 km and a size of 2.66 ㎢, designated as Natural Monument No. 179, Daejeo Ecological Park is a habitat for migratory birds at the Nakdong River Estuary. The estuary was chosen as a trial project for the Four Major Rivers Restoration Project. The sports facilities were partially built on the upper and lower parts of the park only, while the rest of the park underwent a restoration of its wetlands and natural grassland. In the garden inside the park, you can find a large-scale habitat for prickly water lilies, which are part of the Endangered Species Level II classification. Many interesting festivals, such as the Nakdong Riverside Cherry Blossom Festival, the Busan Nakdong River Canola Flower Festival, and the Daejeo Tomato Festival are held around this park every year.
